UK based micro chip designer ARM have told employees that they are not to work with Chinese firm Huawei.
Documents seen by the BBC reportedly tell staff to suspend “all active contracts, support entitlements, and any pending engagements.”
The Cambridge based technology company licenses processor designs that most smartphones around the world have.
ARM is concerned that they could be affected by President Trumps White House executive order over dealings with Huawei as the micro chip firm designs use “US origin technology.”
A spokeswoman for ARM said, “ARM is complying with all of the latest regulations set forth by the US government.”
